GAS STEAM" BADTATOH.

Application filed. Getober 23, 1923.

This invention relates to heating devices of the character employed for heating rooms, buildings and residences.

It is an object of the invention to provide a heater of this character, using gas as fuel, and employing steam for transmission and convection of heat produced by the combustion of the gas.

It is a further object of the invention to provide a gas radiator in which the temperature of the outwardly disposed mem hers is determined by the temperature of the steam contained therein; the said members therefore cannot become heated to a dangerous temperature which would cause serious burns.

It is a further object of the invention to provide a radiator which will quickly heat when the burners thereof are lighter and which will deliver a maximum amount of heat from the fuel employed.

It is a still further object of the invention to provide a radiator having the afore mentioned characteristics which may be economically manufactured and assembled and will be automatic in control.

The especial advantages of the invention and further objects thereof will be made evident hereinafter.

Referring to the drawings which are for illustrative purposes only:

Fig. 1 is a view showing a radiator embodying the features of my invention.

Fig. 2 is a section taken on the plane represented by the line 22 of Fig. 1.

Fig. 3 is a section taken on the plane represented by the line 3-3 of Fig. 2.

Fig. 4 is a section taken on the plane represented by the line 41- 1- of Fig- 3.

Fig. 5 is a section taken as indicated by the line 55 of Fig. 3.

Fig. 6 is a diagrammatic plan view showing the manner in which the radiator sections may be built up into any desired length in order to obtain a heating unit of required capacity.

In the small form of my radiator shown in Fig. 1, a pair of end sections 11 and 12 and a central section 13 are employed. The sections are preferably cast in metal such as cast iron and are suitably cored to provide the internal structure shown. The end sections 11 and 12 are provided with legs 15, and walls 16 which enclose a space which may be termed a combustion chamber sec tion 17. The central section 13 is also pro- Serial No. (H0258.

vided with walls 16 which enclose a combustion chamber section 18, and centrally upwardly from the combustion chamber section 18 the walls 19 extend in the form of a hollow leg or flue 20. This hollow leg 20 serves as a passage for the combustion gases from the combustion chamber and is situated between the two downwardly extending legs 22 of a steam chamber 23, the upper portion of which extends across the upper end of the leg 20, as shown at 21. The steam chamber is enclosed by walls 2 1 which are cast integrally with the rest of the section 13. The walls 19 and 2 1 join at positions 25, slightly above the end wall 26 of the leg 20, and thereby form a depression or bowl 27 at the upper end of the leg 20. The section 11 and the section 12 are provided with steam chambers 29 consisting of the three tubular sections 30, 31 and 32 which intercommunicate at their upper and lower ends so that the steam and water may readily circulate therein. The sections are provided with .interengaging male and female extensions 34 and 35 on a line with the combustion chamber sections 17 and 18, these extensions fitting one with in the other to provide a continuous intercommunication between the combustion sections in order to form a continuous combustion chamber. Near the upper ends of the sections 11, 12 and 13, interengaging projections 38 and 39 are formed for the purpose of aligning the upper ends of these members.

Through a filling spout 10 having a plug -41 water is poured into the lower portion of the steam chamber 29 forming part of the leftward end section 12, this water flowing through connectors 13 which are threaded between the members 11., 12 and 13, filling the lower portions of the steam chambers with water to the level indicated at 15. When the burner is lighted the flames thereof play upwardly against the bottom walls 51 of the steam chambers formed in the members 11 and 12 and against the bottom walls 52 of the member 13. The combustion gases, passing upwardly within the leg 20, heat the walls 19 and 26 thereof, with the result that any water which has con densed at 56 in the bowl 27, is heated and the body of water indicated at 15 in the lower portions of the. steam chambers is also heated, causing the formation of steam in the steam chambers. This steam conveys the heat to the various walls of the steam chambers, from whence it is given ofi into the air which circulates upwardly between and around the tubular portions presented by the radiator. At the upper ends of the steam chambers, connectors 55 are placed for permitting an equalizing of steam pressure between the members 11, 12 and 13. It will be seen that the outwardly presented walls of the radiator sections all constitute walls of a steam chamber and the heat thereof is thereby controlled and determined by the heat of the steam within the chambers, therefore, there is no danger at any time of articles being ignited by contact with the surface of the radiator and the danger of being seriously burned due to inadvertently touching the radiator is eliminated. The outwardly disposed walls of the radiator will rarely exceed a temperature of 220 or 230 degrees Fahrenheit, whereas it will be seen that a metal member in direct contact with a flame may be heated to avery high temperature and serious burns result from personal contact therewith.

The steam chamber communicates through a. pipe 60 with a diaphram 61, the action of which, through a rod 62, controls a gas valve 63 and has the purpose of controlling the operation of the burner 50 in such a manner that the temperature produced thereby in the steam chambers cannot exceed the temperature corresponding to a given steam pressure. The specific type of burner employed does not constitute a part of this invention'and may be one of various forms and will not be described in detail. This burner may be fed from a manifold 70 leading from the regulating valve 68 and the shutoff valve 71.

A simple form of the invention has just been described in which three radiator sections are employed. It will be plainly evident, however, that the size of the radiator may be quickly increased by placing a greater number of intermediate sections 13 between the end sections 11 and 12. In Fig. 6 is indicated a five section radiator consisting of end sections 11 and 12, between which are disposed intermediate sections 13 of the type shown in the previous figures. The interengaging extensions of the sections 13 are so formed that any number of the sections may be placed together in a consecutive arrangementand secured together by the connector members 43. The principles of operation are the same whether the greater or smaller number of sections is employed, as the features previouly described are at all times present.

I claim as my invention:

1. In a heating device, the combination of: a hollow structure forming a combustion chamber; a vertical leg extendin upwardly from said combustion chamber; walls forming a steam chamber extending vertically upward adjacent to said vertical leg and across the top thereof; walls forming a bowl above said vertical leg and in open comunication with said steam chamber, said bowl being so placed as to collect condensaticn forming in said steam chamber; and a burner in said combustion chamber.

2. in a heating device, the C()11'll)l':1tltl011 of: a hollow stru :ture forming a (.(HlllHlltlUll chamber: a vertical extemling upwardly from said combustion chamber; walls form ing a steam chamber extending vertically upward adjacent to said verti al leg and across the top thereof; walls forming a bowl above said vertical leg and in open communication with said steam chamber, said bowl being so placed as to collect condensation forming in said steam chamber; a flue extending through said steam space and so placed as to withdraw products of combustion from the top of said vertical leg; and a burner in said combustion chamber.

3. in a heating device, the combination of: a hollow structure forming a combustion chamber; a vertical leg extending upwardly from said combustion chamber; walls forming a steam chamber extending vertically upward adjacent to said vertical leg and across the top thereof, the lower portion of said steam space forming a receptacle for water directly over said combustion space; walls forming a bowl above said vertical leg and in open communication with said steam chamber, said bowl being so placed as to collect condensation forming in said steam chamber; and a burner in said combustion chamber.
